To all whom it may concern: other side with the motor or other gas utiliz- Be it known that I, FREDERICK W. STEIN, ing appliance which is not shown as same citizen of the United States, residing at forms no part of this invention. Chicago, in thecounty of Cook and State of 8 represents a vertically arranged pipe the 5 JIllinois, have invented certain new and uselower end of which enters the tank 4 near its ful Improvements in Carbureters, of which bottom and the upper end of which is prothe following is a specification. vided with an adjustable conical valve 9 by This invention relates to improvements in which the amount of air entering the 11 per carbureters of that type in which gas is genflared end of the pipe 8 may be contro led. 10, erated in considerable volume from hydro- The lowcr end of the pipe 8 communicates carbon oils for use especially in connect-ion directly with a nozzle 10 which is formed with gas engines.

At the ing out the receptacles in which the gas is bottom of each of the tanks 4 and 5 are faugenerated so as to remove any solids or imcets 13 by which the tanks may be drained purities which may exist in the fluids or gas. if desired. The pipe 12 communicates with Other objects of simplicity and economy. the nozzle 10 arranged in the tank 5 while the pipe 12 communicates with the lower portion of the gas reservoir or tank 6.

Secured within the reservoir or tank 6 is a battle plate 14 formed of corrugated sheet metal and so positioned that it will intercept the gases entering the, reservoir from the tank 5 and the corrugated surface will 'aid in the mixing of the gas with the air in said reservoir and break up the gaseous fluid into eddies or whirls which facilitate the mixing operation.

In the mixing chamber 7 is arranged a perforated cylinder 15 which extends across the mixing chamber vertically and is designed to interrupt the passage of the gases through said mixing chamber to the outlet pipe 20. In the top of the mixing chamber is-secured a cap 16 which is provided with V openings 16 and has extending there through a stem 18 of a valve 18 which is in the appliance illustrated in a preferred form in the accompanying drawing which formsa part of this application in which Figure 1 is a longitudinal section taken 35 through the appliance complete; Fig. 2 is a transverse section of one of the tubes which form afeature of the appliance, and Fig. 3

is a vertical section on an enlarged scale of the final controlling device, which forms a application.

Referringto the drawing in detail, 4, 5, and 6, respectively, represent three tanks which as shown are arranged tandem in the in any other manner which may be found convenient or desirable.

7 is a mixing chamber which communicates with the tank 6 at one side and at the carbureter gasolene is poured into seated in said cap. On the upper end of the valve stem 18 is secured a nut 19 between which and the top of the cap and surrounding the stem is an expansion coiled spring 17 which normally holds the valve 18 on its seat and thus prevents the entrance ofair to the cylinder 15.

In the operation and use of my improved 4 by removing the screw cap 4 until the tank is partly filled. The valve 9 is opened to permit air to enter the pipe 8 from which it escapes through the perforations inthe coils of the nozzle 10 into the fluid inthe tank 4. The gas generated by the gasolene flows with the air that has escaped through '1 the nozzle 10, arises to'the top of the tank 4: and enters the pipe-11, passes out through through the chamber 7 after coming in conher.

tact' with the cylinder 15 and if the valve 18 is open with the air admitted to said chain- It will. be understood of course that this action takes place when the gas is being exhausted or-used from the pipe 20 thus creating a circulation through the several tanks, nozzles and pipes described. Inas-' much as the tank 5 provides" for a substanture of gases.-

tial quantity of gas it will be more or less agitated by the incoming gas and the outflowing gas and effective admixture of air and gas will take place in said tank. If, however, the gas should be toorich for the best result the operator by opening the valve 18 can admit more air so that the gas flowing to the motor or gas user will be of the right quality.

If desired, valves of well knowniforms may be placed in the pipes 12, 12*, thus controlling the passage of the gas from one tank to the other.

The convolution of the walls of the nozzle 10 will cause a whirling of the air or gas injected through said nozzle which, as is well known, contributes to a perfect mix- The connections between the pipes 11, 12, and their respective tanks, will bemade gas and air tight by suitable packing devices and nuts of well known form.

The nozzle 10 in the tank 4: will servev as a filter for the incoming air thus arrestin solids and particles which it is undesira le to have enter the gasolene and the corresponding nozzle in the tank 5 will have the same e ect upon impurities in the the tank gas entering. said tank from the tank 4.

These nozzles therefore serve the purpose of conductors having an extended area and also as filters, also to .set up a whirling motion in the products introduced thereby.

Various other advantages of operation may be found "in this invention which need not be set forth in this connection.

A carbureter composed of a plurality of communicating tanks, meansfor introducing a gas generating fiuid into one of the tanks, and means for introducing air into said tank and a tapering nozzle arranged in said'tank, said nozzle having its walls in the form of spirals and having per-' forations therein for the purpose set forth, and means for conducting the gases generated in said tank into a suitable reservoir.
